Help for GDR DAP application Reference Map
The Reference Map, also know as the key map, is located directly
below the Main Map Area. The Reference Map displays
the area visible on the Main Map View, using a red box or cross hair.
The Reference Map can also be used as a navigation tool. Clicking on
it will shift the Main Map View to be centered on that point without changing
scale.
